PCM1865: Current Consumption

Sadanori Kato
Guru 36540 points
Part Number: PCM1865


Hi,

Could you please fill the blanks in the following list about the current consumption if you have the evaluation data for PCM1865 ?

<Condition>
CH    = 4ch
Ta    = 25degreeC
AVDD  = 3.3V
DVDD  = 3.3V
IOVDD = 3.3V
Mode  = Master
SCLK  = XTAL

Best regards,
Kato

    Hi, Kato-san,

    Could you please clarify that the information you are requesting  corresponds to total power consumption?. Currently we don't have this data available for different SCK clock rates and sample rate combination, so we need to measure this with an EVM and it will take a couple days.

    Hi Diego-san,

    Thank you for your quick response.

    Could you please refer to the following information which I would like to request to you and give me the current consumption ?

    Case 1. 44.1kHz@fs
    - CH              = 4channel
    - XTAL Input      = 22.5792MHz(512 x fs)
    - Mode            = XTAL Master Mode
    - AVDD/DVDD/IOVDD = 3.3V
    - Ta              = 25degreeC

    Case 2. 48kHz@fs
    - CH              = 4channel
    - XTAL Input      = 24.576MHz(512 x fs)
    - Mode            = XTAL Master Mode
    - AVDD/DVDD/IOVDD = 3.3V
    - Ta              = 25degreeC

    Case 3. 96kHz@fs
    - CH              = 4channel
    - XTAL Input      = 24.576MHz(256 x fs)
    - Mode            = XTAL Master Mode
    - AVDD/DVDD/IOVDD = 3.3V
    - Ta              = 25degreeC

    Case 4. 192kHz@fs
    - CH              = 4channel
    - XTAL Input      = 24.576MHz(128 x fs)
    - Mode            = XTAL Master Mode
    - AVDD/DVDD/IOVDD = 3.3V
    - Ta              = 25degreeC

    Best regards,
    Kato

    Hi, Kato-san,

    Please refer to below data. I would like to point out that this data was captured in a bench test with the PCM1865EVM, so the values are an approximate to the device's characteristic power consumption. 

    Sample Rate (Hz) Total current  (mA)
    48K 43.53
    96K 51.04
    192K 60.23

    Hi Diego-san,

    I have additional requests.

    - Each Current Consumption for 4CH
    Could please tell me each current consumption for AVDD, DVDD and IOVDD power supply at 48kHz, 96kHz and 192kHz processing ?

    - Current Consumption for 2CH
    Could please tell me the current consumption only when using 2channel at 48kHz, 96kHz and 192kHz processing ?

    Best regards,
    Kato
